Question

water and acid ratio 4:5 . 20℅ of total solution replace by water. find new ratio​

Answer 1

Answer:

Step-by-step explanation:Let total mix is 5x

Milk is 3x and water is 2x

Removed is 20 liters and balance is 5x-20

(5x-20)*3/5 : (5x-20)*2/5+20 :: 2:3

(5x-20)9/5=(5x-20)*4/5 +200/5

45x-180=20x -80+200

25x=300

x=300/25=12

Initial quantity of milk is 36 liters , water is 24 liters . Total mix is 60 liters

Verification:

Once 20l removed then mix is 40lit . milk is 24lit and water is 16 lit

When 20 lit water added then milk is 24 lit and water is 36 lit. So ratio is 2:3 . It matches .

Initial quantity of milk is 36 liters
